ROTARY PUMP FOR BEVERSING-ENGINIES.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application flied September 26,1910, Serial No. 583,952. Renewed January 12, 1912. Serial No. 670,952.

Be it known that I, JUsrUs R. Kmnnv, a citizen of the United States of America, and a resident of Boston, in the'county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Rotary Pum s for Reversing-Engines, of which the to lowing is a specification.

This invention relates to rotary pumps and has for its particular object the production of a pump that may be used in connec tion with reversing engines and maintain a continuous flow of fluid in one direction without regard to the direction of rotation piston.

The mvent-ion consists of certain novel features of construction and arrangement of parts which will be readily understood by reference 'tothe description of the drawings Of the drawings: Figure 1 represents it features of the present invention. Fig. 2

1, and Fig. 3 represents a transverse section of the same, the cutting plane being on line .3, 3 on Fig. 1.

Similar characters designate like arts throughout the several figures of the di'aw- In the drawings, 10 represents a casing provided with a cylindrical piston chamber 11, with which communicate two auxiliary chambers 12 and 13. Centrally disposed within thepiston chamber 11 is a revoluble shaft 14, having formed thereon an eccentrio 15, on which is mounted the annular piston member 16 a portion of the periphery of which is always in contact wit-h the inner wall of the piston chamber 11. This annular member 16 is rovided with a radial blade 17 inter sed tween the. passages 18 and 1.9, lea ing respectively to the mixiliary chambers 12 and 13. The blade 17 eifectually prevents the passage of anf; fluid from one auxiliary chamber to the ot er except as it is forced by means of the piston 16 through the piston chamber 11. On one side of the auxiliary chambers 12 and 13,

' and in the same horizontal planetherewith, E

is .an inlet compartment 20, while on the opposite side in thersame horizontal plane therewith, is an out-let compartment 21.

Threaded into the wall between the auxiliary chamber 13 and the compartment 20 is a valve casing 22, in which is sitioned a ball 23, having a movement longitudinally of said casing 22, its outward movement bemg limited by a pin 24., extending through said valve casing. Said casing is provided with a valve seat 25, against which the ball 23 may be forced to close the said valve'and prevent the passage of fluid therethrough. In alinement with the valve casing 22, and threaded intothe wall between the auxiliary chamber 13 and the compartment 21 is a similar valve casing 26. In like manner a valve casing 27 is threaded into the wall between the auxiliar chamber 12 and the compartment 20, an in alinement therewith, threaded into the wall between said auxiliary chamber 12 and the compartment 21, is a valve casing 28. All of these valve casings, 22, 26, 27 and 28 are alike, and each is provided with a seat 25 and a pin 24, between which and said seat 25 the ball 23 is free to move. Each valve casing is provided with a hexagonal flange 29, centrally disposed between its two ends, while the periphery of the body portion of said casings on either side of said flange 29 is threaded as at 30 so that said valve casings may be reversed when desired and inserted into the walls with the enlarged open end outward as indicated in the upper part of Fig. 2, or with the enlarged open end inward as iiidicated in the lower part of Fig. 2. When the valves are positioned as indicated in said Fig. 2, and fluid is admitted to the compartment 20 through the opening 31, and the shaft 14 is rotatin in the direction of the arrow a on Fig. 1, the suction caused by the rotation of the piston 16 will cause the ball 23 in thevalve casing 22 to he moved ainst the pin 24, thus permitting the fiui in the compartment 20 to pass through the said 'valve casing 22 into the auxiliary chamber 13. The rotation of the piston 16 will cause the fluid to be drawn through the passage 19 into the piston chamber 11, and forced through said piston chamber and assa e 18 into the auxiliary chamber 12. This ow of fluid into the auxiliary chamber 12 will cause the ball 23 in the valve casing 27 to be moved against the seat 25 and eifectually prevent the passage of any fluid through said valve casin 27 into the compartment 20. The force 0 the fluid will, however, cause the ball 23 in the valve casing 28 to be moved against the 'sto'p' pin and open valve so that the fillld may pass into the compartment 21 and therefrom through'the -outlet 32. The suc' iitioncaused by the rotation of the piston 16 will cause the ball 23in the valve casing 26 to be drawn to its seat andclose this valve,

, preventing the passage of fluid through .said valve casing into the compartment 21 partment 20through the inlet opening 3%" 2 wouldass therefrom-through the outlet 32 with t e rest of" the fluid being 'forced through the valve 'casin 28. Should the shaftul valve casing would be drawn-over to its stop pin 24 and the fluid entering the comwould pass through said valve casing and be forced through the passa'ge l8to the any return of the'fluid into the c'ompart-- meat 20. The fluid entering the auxiliary piston Ichamb'er' 11 into the passage 19 and aum'li" hamber 13, the pressure therein causin a ball 23 in the valve casing 22 to be orced against the seat 25 preventing chamber 13, forcing the ball 25 in the valve casing 26 to its stop pin 24, thus permitting the fluid to pass intothe compartment 21 tobe discharged through the outlet 32. It is' obvious, therefore, that with a device constructed as is herein set forth, the rotation of the piston-16 may be in either direction without changing the direction of the flow of fluid. Obviously this is of great advan-o tage in connection with 'reversmg engines where it is desired to maintain the flow of fluid continuously in one direction. I It is believed that the operation and many advantages of a device of this construction will" be readily understood without any further description.
